features

The olive cap leaf tyrant reaches a body length of about 11.5 to 12 centimeters. The top is light olive green and becomes noticeably darker at the crown. The parting is colored gray. The foliage bully has a showy white eyebrow. The area around the ears is pale yellow with soot-gray spots. The wings and the tail are dark brown, with the individual feathers having okra-colored edges. On the upper part of the wings there are two striking orka-colored horizontal stripes. The control springs are outlined in yellow-brown. The chin is white. The neck, chest and sides are green-yellow, but become lemon-yellow towards the belly.

Habitat

The bird moves at heights between 1000 and 2000 meters. It occurs preferentially in tropical and subtropical zones. You can find it in the mountain rainforest on the slopes and peaks of the Tepuis .

behavior

The bird finds its food in the upper parts of the trees. The olive-cap leaf tyrant is more of a loner. You rarely see him in smaller groups. He is rather calm and behaves inconspicuously. He prefers to peck his food from the leaves of the trees.

Subspecies

Two subspecies of the olive cap leaf tyrant are known:

  • Phylloscartes chapmani chapmani ( Gilliard , 1940) occurs in southern Venezuela.
  • Phylloscartes chapmani duidae ( Phelps & Phelps, WH Jr , 1951) is common in southeastern Venezuela.

Occurrence

The subspecies P. chapmani chapmani is found on the tepuis in the south of the state of Bolívar and the north of the state of Amazonas , as well as the immediately adjacent parts of Guyana and Brazil. The subspecies P. chapmani duidae can be found at Cerro Duida in the Duida-Marahuaca National Park and at Pico da Neblina .

Etymology and history of research

The olive cap leaf tyrant was first described in 1940 by Ernest Thomas Gilliard under the scientific name of Phylloscartes chapmani . The type specimen came from Arabupu in the Roraima Mountains and was collected by Albert Sidney Pinkus . As early as 1859, Jean Louis Cabanis and Ferdinand Heine junior introduced the new generic name Phylloscartes . This name is made up of "pōgōn, pōgōnos πωγων, πωγωνος " for "beard" and "trikkos τρικκος " for "a small bird according to Hesychios of Alexandria ". The species name »chapmani« is dedicated to Frank Michler Chapman . »Duidae« refers to the »Cerro Duida«, the place where Ramón Urbano collected the type specimen on November 20, 1950.
